Helium leak detector analyzer is a tool that is used to test the amount of oxygen inside the sealed package. This is an essential part of Modified Atmosphere Packaging (MAP) as excess O2 can lead to a number of negative consequences for packaged products including spoilage, bacteria and reduced product shelf life. These robust and portable instruments are designed to ensure that the residual O2 concentration in your food or pharmaceutical packaged products meet predefined quality standards by detecting instances where this is not the case.

Detecting Leaks: Exploring the Function of Helium Leak Detectors

The device uses the tunable diode laser absorption spectroscopy method of headspace analysis to measure the contents of the container headspace, i.e. the air volume between the inner seal and the freeze-dried drug product in a sealed parenteral container. The oxygen concentration in the headspace is determined by measuring the absorption of light at a specified frequency – the more oxygen molecules in the headspace, the more the laser light will be absorbed and the signal intensity will decrease. This measurement technique is non-destructive and easy to use making it a very convenient inspection method for a variety of container types such as glass tubular, molded and clear and amber jars and plastic packages used by the pharmaceutical, cosmetic and food industries.

These portable headspace oxygen testing machines are very simple to use and come pre-calibrated with a high-quality electrochemical sensor. Simply pierce the package with the needle and press the pump button to draw sample to the sensor and a real-time O2 graph will display on the screen. The O2 levels can be displayed in either ppm or percent O2. A large, color display makes it easy to read with easy to understand graphics and intuitive operation. USB recharging and data logging are included and the system is IP67 waterproof, dust-proof and explosion-proof exceeding Exib IIB T4 Gb.
